BACKGROUND

All drum washing machines use drainage pumps as active drainageequipment so as to be suitable for more complex using environments andsupply better use feelings for users. A drainage pump of a traditionaldrum washing machine mainly runs in stages of drainage after washing,drainage after rising and dewatering in an integral washing procedure.But, with development of society, the water resource becomes more andmore important, and drum washing machines capable of recycling the waterresource emerge as the times require.

As the drum washing machine needs to recycle the water, the drainagepump not only needs to have a drainage function of the traditional drumwashing machine, but also needs to have a function of draining drainedwater to a water treatment system and enabling the drained water toreturn to the drum washing machine. For example, a mode that twodrainage pumps are mounted can be adopted to realize the functions,wherein one drainage pump controls drained water after washing ordewatering to be drained out of the washing machine, and the otherdrainage pump controls drained water after washing to be drained to awater reusing system, so that the two drainage pumps need to be mountedat the same time, not only is the mounting complexity increased, butalso the manufacturing cost is increased to a certain extent.

A drainage pump suitable for the drum washing machine with the waterreusing function exists, and the drainage pump integrates the twodrainage pumps. According to a conventional drum washing machine, thedrainage pump is generally and directly fixed to a bottom plate of thewashing machine with screws or is indirectly fixed through a rubberwasher when being fixed. The fixing manner causes poor damping effects,and the condition that the vibration of the drainage pump is transferredto the main body of the washing machine and transferred to outsidecannot be well avoided, and high vibration and noise are generated whenthe drainage pump operates.

According to the conventional Chinese patent No. CN201410242349.6 named“Damping Cushion of Drainage Pump and Mounting Structure of DampingCushion”. The conventional present disclosure relates to a drainage pumpof a drum washing machine and a mounting structure of the drainage pump,wherein a supporting frame and L-shaped supporting legs are respectivelyarranged on two sides of the lower part of the drainage pump, a mountingplate is arranged at the lower part of the supporting frame and at leastone fixing hole is fixed in the mounting plate. A cylindrical screwpillar is arranged on the bottom plate of the washing machine, and anassembling groove is formed in the bottom plate, on one side of thescrew pillar. The support frame of the drainage pump is connected withthe bottom plate of the washing machine through a first damping cushionand the screw pillar, and a second damping cushion can sleeve each ofthe L-shaped supporting legs of the drainage pump and is embedded in theassembling groove. The mounting damping device disclosed by thedisclosure is simple and compact in structure, and convenient andefficient to mount, the drainage pump is mounted on the bottom plate ofthe washing machine through the support frame, the L-shaped supportinglegs, the first damping cushion and the second damping cushions, so thatvibration transfer when the drainage pump operates is reduced, thevibration and the noise of the washing machine are effectively reduced,the using feelings of users are improved, and the product quality of thewashing machine is improved.

The damping cushion is difficult to mount, the number of needed dampingcushions is large, the needed damping cushions are inconsistent, thedamping cushion is difficult to assemble, the structure of a fixingbracket is complex, and processing and making are not easy. Therefore,how to realize fixed mounting of the drainage pump, and how to realizedamping so as to prevent high noise from being generated become atechnical problem to be urgently solved.

Embodiment 1

As shown in FIG. 1, FIG. 2, FIG. 3, FIG. 4 and FIG. 5, this embodimentis a double-head drainage pump of a washing machine, and particularlyadopts the following technical scheme.

A double-head drainage pump of a washing machine comprises a pumphousing in which a water inlet 8 is formed, at least one first wateroutlet 2 and at least one second water outlet 6 are formed in the pumphousing. A first drainage motor 1 is mounted on the pump housingcorresponding to the first water outlet 2 and a second drainage motor 10is mounted on the pump housing corresponding to the second water outlet6. The first drainage motor 1 controls opening/closing of the firstwater outlet 2, and the second drainage motor 10 controlsopening/closing of the second water outlet 6.

The double-head drainage pump of the washing machine of the presentembodiment, the first water outlet 2 and the second water outlet 6 whichshare one water inlet are formed in the pump housing. The first wateroutlet 2 is used for realizing drainage of the washing machine, and thesecond water outlet 6 is used for realizing water reusing drainage, sothat the double-head drainage pump of the embodiment can be suitable fora drum washing machine with a water reusing function and is high inintegration level of the whole structure, simple in structure and easyto mount.

The pump housing of the double-head drainage pump of the embodiment atleast comprises a first pump housing 4 and a second pump housing 9 whichinternally communicate with each other. The water inlet 8 and the firstwater outlet 2 are respectively formed in the first pump housing 4, andthe second water outlet 6 is formed in the second pump housing 9. Thefirst drainage motor 1 is mounted on the first pump housing 4, and thesecond drainage motor 10 is mounted on the second pump housing 9.

The pump housing of the double-head drainage pump of the embodimentrealizes internal communication but is not integrally designed, andcomprises two parts including the first pump housing 4 and the secondpump housing 9 which realizes internal mutual communication, so that thefirst pump housing 4 and the second pump housing 9 can be separatelydesigned according to actual drainage needs. Particularly, the firstpump housing 4 and the second pump housing 9 depends mainly on drainagelifts of the first water outlet 2 and the second water outlet 6, andgenerally, the larger the drainage lift of drainage hole is, the largerthe volume of the arranged pump housing is.

However, because the second water outlet 6 is connected to a waterreusing system in the actual process, and the water reusing system needsto carry out a filter process on washing water, the drainage lift of thesecond water outlet 6 of the double-head drainage pump is smaller thanthat of the first water outlet 2 of the present disclosure so as toensure sufficient filtering to reach good filtering effects. Therefore,the volume of the second pump housing 9 of the double-head drainage pumpis smaller than that of the first pump housing 4 of the presentdisclosure. In addition, with the design that the volume of the secondpump housing 9 is smaller than that of the first pump housing 4, thevolume of the whole structure of the double-head drainage pump of theembodiment can be reduced, so that too long length of the double-headdrainage pump in a certain direction is prevented, and mounting is moreconvenient.

Therefore, the double-head drainage pump of the embodiment realizes theeffects of water reusing and drainage and can replace the followingcomplex structures and parts, such as a three-way valve, and the like.

In the present embodiment, because the design manner that the volume ofthe second pump housing 9 is smaller than that of the first pump housing4 is adopted, the water inlet 8 needs to be formed in the first pumphousing 4, so that the water inlet quantity of the water inlet 8 can beincreased as much as possible. It ensures smooth water outgoing of thefirst water outlet 2 and the second water outlet 6 and avoids thecondition that drainage discontinuous of the drainage holes as the waterinlet quantity of the water inlet 8 is limited by the volume of thesecond pump housing 9.

Specifically, a third water outlet which communicates with the waterinlet 8 is also formed in the first pump housing 4 of the presentembodiment, and the second pump housing 9 is connected with the thirdwater outlet so as to realize internal mutual communication between thefirst pump housing 4 and the second pump housing 9.

The first pump housing 4 of the double-head drainage pump of theembodiment comprises a first pump housing body 401, a water inlet pipe402, a first water outlet pipe 403 and a third water outlet pipe 404.Wherein the first pump housing body 401 is internally provided with ahollow channel, the water inlet pipe 402, the first water outlet pipe403 and the third water outlet pipe 404 communicate with the hollowchannel of the first pump housing body 401 separately. And the waterinlet 8, the first water outlet 2 and the third water outlet arecorrespondingly formed in the end parts of the water inlet pipe 402, thefirst water outlet pipe 403 and the third water outlet pipe 404.

Drained water of the drum washing machine of the embodiment enters theinternal hollow channel of the pump housing body 401 of the first pumphousing 4 through the water inlet pipe 402 and then separately entersthe first water outlet pipe 403 and the third water outlet pipe 404which communicate with the hollow channel. And the drained water in thethird water outlet pipe 404 enters to the second pump housing 9 so as toseparately introduce the drained water into the two pump housings.Drainage of the drained water in the first pump housing 4 is controlledby the first drainage motor 1 and the second drainage motor 10separately, while the drained water in the second pump housing 9 is onlycontrolled by the second drainage motor 10.

As a preferred implementation of the embodiment, the water inlet pipe402, the first water outlet pipe 403 and the third water outlet pipe 404communicate with the side wall of the first pump housing body 401, thethird water outlet pipe 404 and the water inlet pipe 402 are arranged ona same plane, and the third water outlet pipe 404 and the first wateroutlet pipe 403 are arranged on different planes. In this way, thesecond pump housing 9 is arranged on one side of the first pump housing4 in the manner that the second pump housing 9 and the first pumphousing 4 are in parallel, and the whole axial length of the double-headdrainage pump of the embodiment is reduced.

Further preferably, the third water outlet pipe 404 and the water inletpipe 402 are arranged on the same side of the first pump housing body401. In this way, the second pump housing 9 and the water inlet pipe 402are arranged on the same side of the first pump housing 4, so thattransverse width during mounting is reduced, and mounting is moreconvenient.

For enabling drainage to be smooth and residual pollutants tosuccessfully flow into the pump housing so as to facilitate manualcleaning, as a preferred implementation of the present disclosure, thewater inlet 8 of the water inlet pipe 402 is formed in the manner ofslanting upward by 5-15 degrees.

How to realize communication between the second pump housing 9 and thefirst pump housing 4 is an important technical problem to be solved inthe embodiment, and specifically, the following two technical schemescan be adopted.

Scheme I is that the third water outlet pipe 404 of the embodiment is anL-shaped pipeline, one end of the third water outlet pipe 404 integrallycommunicates with the side wall of the first pump housing 4, and theother end integrally communicates with the inner part of the second pumphousing 9. In this way, the first pump housing 4 and the second pumphousing 9 are integrally formed, the industrial integration degree ishigher, and the assembly is simpler and more convenient.

Scheme II is that a second pump housing water inlet 901 whichcommunicates with the second water outlet 6 is formed in the second pumphousing 9 of the embodiment and is connected with the third water outletof the first pump housing 4 Specifically, the second pump housing waterinlet 901 communicates with the third water outlet of the first pumphousing 4 through a connector 15, and preferably, the connector 15 is asoft water pipe. In this way, the first pump housing 4 and the secondpump housing 9 are assembled after being separately processed, so thatprocessing is simpler, connection is easier to realize by adopting asoft water pipe, and the processing accuracy requirements are reduced.

In a word, the first pump housing 4 and the second pump housing 9 arearranged in a split mode, and the second pump housing 9 communicateswith the first pump housing 4 through the connector 15; or the firstpump housing 4 and the second pump housing 9 are integrally formed.

As a preferred implementation of the present embodiment, the whole bodyof the first pump housing 4 of the embodiment adopts a columnarstructure with a hollow channel inside, specifically a cylindricalstructure. An end part of one end of the columnar structure is providedwith the first drainage motor 1, and the water outlet direction of thefirst water outlet 2 is vertically upward, i.e., the axis of the firstwater outlet 2 is arranged perpendicular to the medial axis of thecolumnar structure. An end part of the other end of the columnarstructure is a disc-shaped first pump housing mounting part 5, athreaded mounting hole is formed in the first pump housing mounting part5. And the first pump housing 4 is mounted on the inner wall of a frontpanel of the drum washing machine through threads. The third wateroutlet pipe 404 and the water inlet pipe 402 both communicate with theside wall of the columnar structure and are located on the same side.

As a preferred implementation of the embodiment, the drainage lift ofthe second water outlet 6 is smaller than that of the first water outlet2. Specifically, the drainage lift of the second water outlet 6 is0.2-0.8 m, so that the second water outlet 6 is more suitable foreffectively carrying out filter treatment on reused water in the waterreusing system.

As a preferred implementation of the embodiment, a first check structure3 is arranged on the first water outlet 2, a second check structure 7 isarranged on the second water outlet 6. The second check structure 7 isintegrally formed by a soft material and comprises an annular mountingpart 703 and a disc-shaped check part 701, the mounting part 703 sleevesthe pipe wall of the second water outlet 6, and the check part 701covers the second water outlet 6.

The check structure is arranged at each of the two water outlets of thedouble-head drainage pump of the embodiment, so that water reflux can beavoided, and secondary pollution is avoided.

As the drainage lift of the second water outlet 6 is smaller, the insidediameter of the second water outlet 6 is also smaller, and in theembodiment, the second check structure 7 with simple structure isdesigned according to such structure characteristics of the second wateroutlet 6. As shown in FIG. 8, the second check structure 7 is integrallyformed by the soft material and comprises the mounting part 703, thecheck part 701 and a connecting column 702 for connecting the mountingpart 703 and the check part 701. The mounting part 703 sleeves the pipewall of the second water outlet 6, and the check part 701 covers thesecond water outlet Gunder a natural state. The check part 701 is openedunder the action of a water flow when the water flow flows out from thesecond water outlet 6 and more tightly covers the second water outlet 6under the action of a reverse water flow. So the second water outlet 6can only carry out one-way drainage, water cannot reversely flow backinto the second pump housing 9, and the check action is realized.Therefore, the second check structure 7 of the present embodiment issimpler in structure, more convenient to mount and obvious in checkeffect.
